CO-PENDING PATENT APPLICATIONS

This Nonprovisional Patent Application is a Continuation Patent Application to Nonprovisional patent application Ser. No. 15/802,452 as filed on Nov. 3, 2017 by Inventor Larry Pulliam. Nonprovisional patent application Ser. No. 15/802,452 is hereby incorporated into its entirety and for all purposes into the present disclosure.

FIELD OF THE INVENTION

The present invention relates to manual gripping of structures and weighted objects.

More particularly, the present invention relates manually accessible grip elements of fixed structures and manually positionable weighted objects.

BACKGROUND OF THE INVENTION

The subject matter discussed in the background section should not be assumed to be prior art merely as a result of its mention in the background section. Similarly, a problem mentioned in the background section or associated with the subject matter of the background section should not be assumed to have been previously recognized in the prior art. The subject matter in the background section merely represents different approaches, which in and of themselves may also be inventions.

Numerous structures and objects, such as ladders, pull up bars and weight training equipment, are intended to manually engaged with by human users. The trend in the prior art is to manufacture gripping elements of such structures to be consistently smooth throughout a round circumference, or to present a consistent surface texture, such as a knurled surfacing. The prior art teaches that such consistency is preferable for cost efficiency and standardization. In one prior art example, competitive weight lifting associations might specify the exact dimensions and weight of weight lifting bar for authorized use in competitions. The prior art teaches that in training for competition it is generally preferred to use the same equipment design that a competitor will be using in an authorized match, meet or competition. When standardized gripping elements are specified to have a continuous circumference, the prior art teaches against even training with a bar that might have an uneven, broken, or inconsistent gripping circumference.

The prior art fails to consider or provide a gripping element intended for manual gripping by a human user that is superior to prior art grips that form a consistent surface throughout an entire circumference of the prior art grip element of the equipment or structure.

SUMMARY AND OBJECTS OF THE INVENTION

Towards these and other objects of the present invention (hereinafter, “the invented grip”) that are made obvious to one of ordinary skill in the art in light of the present disclosure, the invented grip.

A still alternate preferred embodiment of the invented grip provides a pull up bar or other bar attached to a structure, wherein the gripping surface of the instant bar has a hexagonal outer surface forming six surfaces.

A yet alternate preferred embodiment of the invented grip provides kettle bell, a dumbbell and/or barbell exercise equipment that each present a hexagonal outer circumference forming six planar surfaces. The invented grip may optionally be positioned on a curved bar.

A structure or equipment presenting the invented grip may include knurled portions and/or smoothed portions.

Various alternate preferred embodiments of the invented grip include one or more of the following aspects or elements: (a.) an elongate length forming a hexagonal cross-section along first length; (b.) a first attachment end and a second attachment end positioned at separate ends of the elongate length; (c.) the first attachment end and/or the second attachment end each presenting circular cross-sections; (d.) a first attachment end and/or a second attachment end each conforming to a standard weight lifting sleeve specification of the International Olympic Committee of Lausanne, Switzerland or other suitable equipment standards known in the art; (e.) second elongate length forming a hexagonal cross-section; (f.) a first length and a second length symmetrically positioned relative to a central point of a same elongate length; (g.) a first length and the second length each extending within the range of from four inches to eight inches along the elongate length; (h.) a first length and a second length each extending greater than eight inches along the elongate length; (i.) a knurled surface extending partially or fully along an outer surface of an elongate length; (j.) a first smooth ring portion is disposed within a knurling of a first length and a second smooth ring portion disposed within a second length; (k.) a linear relieved section partially extending along a face of the hexagonal elongate length; (l.) one or more linear relieved sections, each linear relieved section at least partially extending along a separate face of a hexagonal elongate length; (m.) at least one linear relieved section, the at least one linear relieved section partially extending along a face of a hexagonal elongate length; (n.) a hexagonal elongate bar conforming to elements of a standard weight lifting equipment specification; (o.) a weighted kettle bell comprising a curved handle coupled to the weight at both a first attachment point and a second attachment point, wherein the curved handle includes a hexagonal cross-section; (p.) a kettle bell handle length extending for less than one half of a full length of a curved kettle bell handle; (q.) a kettle bell handle length extending for greater than one half of a full length of a curved kettle bell handle; (r.) An exercise pull-up bar coupled with an external structure forming a hexagonal cross-section along at a first length.
